Problems solved by technology

Since the biochemical reaction tank has no obvious degradation effect on camellia saponin, the water discharged from the sewage treatment plant still contains camellia saponin, which will not only produce relatively stable foam, but also affect water organisms
If chemical methods are used for processing, not only the cost is high, but also new pollution will be caused, and the structure of camellia saponin will be destroyed, affecting its application value
In addition, if the conventional distillation method is used to evaporate the water in the process water, although the distillate is crude tea saponin, it has many impurities and low purity, and the distillation consumes a lot of energy, which is not economically considered.
Therefore, the problems brought about by the treatment of process water have greatly restricted the application of water substitution method and water enzymatic method in the research and production of Camellia oleifera seed processing technology.

Embodiment 1

[0044] The efficient and clean extraction method of the full-priced Camellia oleifera seed oil and tea saponin is as follows:

[0045] (1) Grind the shelled camellia oleifera seed kernels into the camellia oleifera seed pulp with fully destroyed cells, add deionized water to the camellia oleifera seed pulp and extract at 80°C for 3.0 hours. The weight of deionized water added is 1.8 times the weight of the seed kernel, and after centrifugation, crude camellia seed oil, strong tea saponin liquid and A wet residue are obtained;

[0046] (2) Extract the wet slag A obtained in step (1) with deionized water at 70°C for 1.5 hours to separate the dilute tea saponin solution A and the wet slag B, and return the dilute tea saponin solution A to the step ( 1) Substitute deionized water in the medium as the extracting solution for extracting camellia seed pulp;

[0047] (3) Extract the wet residue of B obtained in step (2) with deionized water at 70°C for 1.0 h to separate the dilute te...

Embodiment 2

[0058] The efficient and clean extraction method of the full-priced Camellia oleifera seed oil and tea saponin is as follows:

[0059] (1) Grind the dehulled camellia seed kernels into a camellia seed pulp with fully destroyed cells, add deionized water and amylase to the camellia seed pulp, extract at 80°C for 1.2-6.0h, deionized water The added weight of the amylase is 1.6 times of the weight of the camellia oleifera seed kernel, and the added weight of the amylase is 0.03% of the weight of the camellia oleifera seed pulp, and after centrifugation, crude camellia oleifera seed oil, strong tea saponin liquid and A wet residue are obtained;

[0060] (2) Extract the wet residue A obtained in step (1) with deionized water at 70°C for 1.0 h, separate the diluted tea saponin solution A and the wet residue B, and return the diluted tea saponin solution A to the step (1) instead of deionized water as the extraction solution for extracting camellia oleifera seed pulp;

[0061] (3) E...

Abstract

The invention relates to a high-efficiency clean extraction method of complete camellia seed oil and tea saponin. The method includes the step that clean recycled water and deionized water or a reverse extraction mode are used for extracting the camellia seed oil and the tea saponin from complete camellia seed kernel slurry. Crude camellia seed oil and strong tea saponin liquid are obtained through centrifugal separation. The crude oil is separated to remove mechanical impurities and subjected to dewatering treatment, the complete original ecological camellia seed oil which does not need refining is obtained, and the oil yield can reach 93% or above. After part of water is evaporated and recycled from the strong tea saponin liquid through an efficient energy-saving MVR technology, alcoholis added for treatment, the mechanical impurities and glue-soluble impurities are removed, and after the clarified alcohol-containing tea saponin liquid is distilled through a closed-loop evaporator and the alcohol is recycled, the product continues to be dewatered and dried to obtain the tea saponin with the purity higher than 60% and clean recycled water which can be used for next extraction.

Description

technical field [0001] The invention belongs to the technical field of agricultural resource utilization. The invention relates to an efficient and clean extraction method of full price camellia seed oil and tea saponin. Background technique [0002] Camellia seed (Oil-Camellia seed) is a unique woody oil plant in China. The oil content of camellia oleifera seed is 18%-35%, and the oleic acid content in camellia oleifera seed oil is between 74%-85%, which is the edible vegetable oil with the highest oleic acid content at present. Camellia oleifera seed oil is rich in functional ingredients such as carotenoids, camellia oleifera saponins, tea polyphenols, squalene and oil-soluble vitamins. Camellia oleifera seed contains 6%-11% protein, which is a potential feed protein. Camellia oleifera seed also contains 10%-15% camellia saponin, which is a natural non-ionic surfactant, easily soluble in hot water and ethanol. Widely used in pharmaceutical, daily chemical, pesticide an...
